Modifying a CYS-S8218 Servo

Ray.Edgley's picture

The CYS-S8218 is a nice beefy servo boasting a 40Kg of torque, which is very impressive.

However, this servo does come with one limitation; it has only a 90 degree of rotation output.

When you look inside the servo, there at physical stops at 220 degree and the position potentiometer is also rated to 220 degree, this suggest a lot of reserve capacity within the mechanics, and the manufacture wanting to prevent model builder from overloading the servo by limiting the range to a point it will always have max torque available.


Walking Robots Part Two

In my previous blog on walking robots I touched on the current open source walking robot progress.

Since that time there has been some progress, with some success. 
Gael Langevin has released a video of his robot knee in operation,https://www.youtube.com/watch?v=9FG0sEBupAQ

Harland has also shown his robot taking its first steps https://www.youtube.com/watch?v=G4LspxN14tw


CMUcam5 Pixy - first impressions

Gareth's picture

Here is some test data that I am working on to check out the capabilities and speed of a CMUcam5 Pixy camera.

I am using two interfaces to set the system up :-

1. USB plugging into the Pixy allowing the PixyMon Gui to monitor,adjust & capture objects (by colour).

2. A connection between the Pixy<> Arduino on the 6pin ICSP port (aka SPI (Serial Peripheral Interface))

NeoPixel Strand Esp8226 Weirdness...

GroG's picture

Ahoy!  - I have a neopixel 300 led strand - I intend to pimp out my Wife's Honda Odyssey as a practical joke..  So this is for a "good cause" ...

I got it working on an Uno, but on the Esp8226 I got "no love" ..

I'm using the Adafruit library, and strandtest sketch "works" on an Uno.

One interesting thing I noticed is when "strandtest" is running - pixels change 3 at a time..
